I'm not sure wwhats been happening these last few months, but I think it has something to do with the most recently moved mobile, (which is often yourself) however I've been stood still and all of a sudden seen (on my ACX) the arrow jump and move in accordance to a monster coming to attack me. Very unusal behaviour!

Well I'm happy to stick with the camera for now, as I have it in over the shoulder view most of the time anyway :)
